Nationalsim with conquest IS bad, Ruth; but nationalism with eco-travel and fair-trade, via a stronger UN, is good for humanity. And, as suggested, quite recently, the questioning of whether it was/is a good idea to have a multiple number of cultures living under the one state law has moved well beyond just "right-wing crackpots" - and given 9/11 and 7/7 one would be foolish not to. (Further, I think questioning ECONOMIC immigration is actually a Left-Wing attitude.)
